The excavations at Nausharo (Pakistan), like all sites of the Indus Civilizations, produced a large number of ceramic vessels, the functions of which are reinterpreted here in the light of recent ethnoarchaeological observations. It is thus possible to identify certain vessels which could have been used for the storage, conservation, transformation and transport of milk products. The presence (or absence) of specific forms such as graters, cheese strainers and jars reflects the technology of a large-scale craft industry. Their discovery on sites at great distance from the Indus, in South-East Arabia and Bactria, indicates the possible limits of Harappan trade and exports in the 3rd. millennium. In the Indus itself, they suggest that urban society was strongly oriented towards the rural and nomadic worlds.
